What do bookmarklets do?

A bookmarklet is a "one-click" tool which adds functionality to the browser, such as modifying the appearance of a web page, querying a search engine with search terms provided by previously selected text, or submitting the current page to a translation or blogging service.

How bookmarklets are different from extensions?

They do basic tasks on clicking.

They are universal, i.e. they usually work on any browser, not just Firefox, and whatever the platform, mobile or desktop.
